The pair both revealed the festive engagement on their Instagram accounts, with Sarah writing: 'So I had the best Christmas Eve of my entire life! My favourite asked me to be his wife and of course I said YES!!!

'I can't put into words the feeling, but I have replayed it my head every 2 minutes since just when I thought I couldn't be happier he goes and tops it! I am literally floating on cloud 9 right now @astonmerrygold I love you with my whole heart and I promise to be the best wife to you.'
